It could be I'm doing something wrong, or maybe my computer is, but when 
I render the following code, I would expect a completely white image, 
instead I get little black dots.
When using "interpolate 3" instead of 2, the problem gets worse, and 
"interpolate 4" gives slightly better results, but still gives me black 
dots.

(I tried to minimize the code)
(also, don't use anti-aliasing when trying this, as it may "cover up" 
those black dots :))
(and also, don't render it the same resolution as the function image, 
because then it won't show)

--- START CODE ---
plane {
   z,1
   #local Function=
     function {
       pigment {
         image_map {
           function 5,5 {pigment {rgbt 1}}
           interpolate 2
         }
       }
     }
   pigment {
     function {Function(x,y,z).red}
   }
   finish {ambient 1}
}
--- END CODE ---

I'm using POV-Ray 3.7.0.RC3.msvc9-sse2.win32 on an Athlon64 X2 5600+ 
with 2GB RAM running Windows XP.

Can anyone confirm this problem?
